Keep in mind that Pictures are very delicate things. Although these presets has been tested on a lot of pictures, sometimes it may not come out so well as on other photos, this is because of the difference in picture quality, lighting, tone and so on… Feel free to tweak in some adjustments to make it look better (If possible).
